AI Thread Summary
A pH of 12 does not indicate that a substance is 10^6 times more basic than a substance with a pH of 6. The pH scale is logarithmic, meaning it reflects the concentration of hydrogen ions (H+) in a solution rather than the inherent basicity of a substance. The ratio of concentrations of H+ or OH- ions is what determines the difference in pH levels. Therefore, while the numerical difference suggests a significant change, it does not directly correlate to basicity in terms of substance properties. Understanding pH requires recognizing it as a characteristic of the solution rather than the substance itself.

Here's a quickie. Since the pH scale is based on powers of 10, would a pH of 12 indicate that a substance is 10^6 times more basic than a substance with a pH of 6?

No. pH is not a property of the substance, it is a property of the solution.

106 is the ratio of concentrations of H+ (or OH-), not directly related to substance basicity.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
